Title: Process for teh preparation of a diene block copolymer
IPC: C08F297/02
Filed: 1972-03-30
Abstract: 1364177 Conjugated diene block polymers SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 30 March 1972 [2 April 1971] 15059/72 Heading C3P A block polymer is prepared by a process comprising the step of (a) polymerizing a conjugated diene in the presence of an organolithium initiator and an ether, thioether, tertiary amine or hexaalkylphosphoranide so as to produce a block having more than 25% of 1,2 or 3,4 microstructure (b) adding a dihydrocarbyl compound of zinc, cadmium, magnesium, calcium, strontium or barium, and (c) polymerizing the same or a different diene whereby a second block containing less 1,2 or 3,4 microstructure than the first is formed. When the same monomer is to be used for both polymerization stages the whole amount of monomer can be charged initially, the dihydrocarbyl compound being added at the desired intermediate stage in the reaction. Step (a) may be preceded by a polymerization carried out in the absence of a polar modifier so that the final product has three blocks, with a low 1,2 or 3,4 content in the outer ones. Alternatively a further amount of the polar modifier, sufficient to nullify the effect of the dihydrocarbyl compound, can be added after step (c), followed by a further polymerization step to give a three-block polymer with a low 1,2 or 3,4 content in the centre block. The lining polymers produced by the process can be deactivated and covered or can be reacted with conventional coupling agents. Examples describe (1) polymerization of butadiene in the presence of sec-butyl lithium and tetramethylethylene diamine with addition of diethyl zinc at an intermediate stage, the product being coupled using phenyl benzoate, and (2) polymerization of butadiene in the presence of sec-butyl lithium followed by addition of tetramethylethylenediamine and isoprene and then of diethyl zinc and butadiene.

Title: Improvements in or relating to a process for recovering finely divided pigments suchas carbon black
IPC: C09C1/58
Filed: 1950-06-22
Abstract: <PICT:0688776/III/1> Finely divided pigments such as carbon black, zinc oxide, calcium carbonate, chromium oxide, magnesium oxide and alumina are recovered from aerosols thereof by forming a slurry by scrubbing the aerosols with an aqueous liquid, agitating a quantity of the same pigment in a dry fluffy state and gradually adding the slurry to the dry pigment, with agitation whereby self-sustaining pellets are formed.  A wetting agent such as an aromatic or aliphatic sulphonic acid may be added to the slurry which may contain 2 to 10 per cent solids by weight, before addition to the dry pigment. The moisture content of the mixture of slurry and dry pigment is preferably between 75 and 25 per cent.  In the carbon black recovery unit shown in the Figure carbon black aerosol, as flue gases from a furnace black plant, enters a cooler 10 where it is sprayed with water at 14 and recycled slurry at 16.  The cooled aerosol then passes to an electric or sonic precipitator 18, cyclone separators 20 and 22 and finally to a scrubber 24 where the residual carbon black is recovered as a slurry in the water injected at 26.  The gases then pass through an electric precipitator 28 before being reheated above the dew point at 32 and exhaustion to the atmosphere.  The slurry is withdrawn from scrubber 24 through pipe 40 to a clarifier 42 from which the upper and lower sludges are transferred to a mixer 48 through pipes 46 and 54 respectively.  Excess water from clarifier 42 is recycled to the scrubber 24.  A wetting agent is added to the mixer 48 through pipe 68 and the resulting slurry is recycled in part to the cooler 10 by pipes 76, 80 and 86 to a bifluid nozzle 16.  The remainder passes through pipes supplied with dry carbon black from the cyclone, 20, 22 and storage tank 88 through line 90.  The finished pellets are passed to a drier 92, and a portion of them, preferably under and oversized pellets, are pulverized at 94 and recycled to the pellitizer 84 to control the solids/water concentration to 3 parts of carbon black to 1 to 9 parts of water.
